stevel05 Expert Licensed User Longtime User Aug 8, 2014 #2 The encoder AMR-NB is the worst quality encoder and is limited to 8khz recording. Try these settings for a reasonable quality recording: Code: Copy Rec.Initialize Rec.AudioSource = Rec.AS_MIC Rec.OutputFormat = Rec.OF_THREE_GPP Rec.AudioEncoder = Rec.AE_AAC Rec.AudioSamplingRate = 44100 Rec.prepare Not all devices support all formats, but these are pretty standard settings so should work. The final quality of the recording will also be dependent on the hardware, and the conditions in the room (background noise etc.) Upvote 0
